In theory a fully charged battery should be 13.8V. This is rarely the case as it depends on temperature as well. In practice 12.5V to 13V indicates a full charge. A far more accurate way of measuring battery charge is with a hygrometer. It measures the density of the electrolite since density is directly related to charge and ultimately the voltage measured across the battery. It is relatively inexpensive and easy to use but will work only if your battery has removable plugs. Unscrew the plug, insert the hygrometer, **** up a small amount of electrolite and take the reading. Do this with all of the 6 cells in the battery. Simple as that.

All batteries are 12 volt a battery is good shape 11.5 to 13 volts.
If your looking at the gauge on the dash with the car running this shows the voltage amount being sent from the alterantor to the battery which should always be above 12 and not more than 14

SOURCE: 2004 VW Jetta engine compartment fuze box location

one is located over the battery, the other is located in the side of the dash.

First panel:
If you pop your hood the battery will be on your right sid in the front of the engine bay. There is a small rectangular piece on top of the battery with a lot of heavy guage red wires going to it. That is the engine bay fuse box.

Second panel:
if you open your driver side car door it's under neath a panel located inbetween the door and the dash board.

SOURCE: how to install a bov on a 2000-2004 vw jetta

It is not wise to install a BOV on a 1.8t since it could cause problems with stalling in between shifts if it is vented to the atmosphere. The most recommended aftermarket solution is a new diverter valve (ex: Baileys, APR etc). If you still want to install the BOV they sell kits for the ssqv that mounts it to the charge pipe and routes the air back to the intake.

I give the same answer to everyone with these symptoms. Have your battery checked for specific gravity and load test. When weather starts to get cold this is a common problem. GOOD LUCK FRIEND.
